TreeView檔案夾結構例外-有解無憂

我有兩個TreeViews，每個都在驅動器上生成一個檔案夾結構。該程式只有 1 個在 2 個驅動器comboBox中構建。TreeViews我只使用一個comboBox，因為幾乎每個檔案夾都有相同的F:名稱Z:

我說幾乎是因為我有 3 個具有相似名稱但不確切名稱的檔案夾。

所以假設我的 DropDown 看起來像這樣：

Book1
Book2
Book3
Book4

所以 Z 上的目錄：看起來像上面的例子，因為那是我的來源comboBox

R：看起來像這樣：

Book1
Book2
Book3_projects_render
Book4

所以我的代碼適用于 Book1、Book2 和 Book4，但是當我在 DropDown 上單擊 Book3 并創建我的 TreeView 結構時，它將在 R 上創建一個新目錄：名為 Book3，我想要實作的解決方案是為目錄設定例外像Book3_projects_render這樣它不會創建一個新目錄。

我的代碼：

public Form1()
{
    InitializeComponent();
    // ...

    loremDropDown.DisplayMember = "Name";
    loremDropDown.ValueMember = "FullName";
    loremDropDown.DataSource = new DirectoryInfo("F:\\").GetDirectories();
}

private void SomeButton_Click(object sender, EventArgs e)
{
    var driveF = "F:\\";
    var driveZ = "Z:\\";
    var selDir = loremDropDown.SelectedValue.ToString();
    var destPathF = selDir.Replace(Path.GetPathRoot(selDir), driveF);
    var destPathZ = selDir.Replace(Path.GetPathRoot(selDir), driveZ);
    var treeSep = pathLorem.PathSeparator;
    var dirSep = Path.DirectorySeparatorChar.ToString();
    var shortcuts = new HashSet<string>();

    foreach (var node in GetCheckedNodes(pathLorem.Nodes))
    {
        var sPath = Path.Combine(destPathF, node.FullPath.Replace(treeSep, dirSep));
        Directory.CreateDirectory(sPath);

        if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveF.ToArray()));
    }

    foreach (var node in GetCheckedNodes(ipsumPath.Nodes))
    {
        var sPath = Path.Combine(destPathZ, node.FullPath.Replace(treeSep, dirSep));
        Directory.CreateDirectory(sPath);

        if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveZ.ToArray()));
    }

    foreach (var shortcut in shortcuts)
    {
        var dirF = $"{driveF}{shortcut}";
        var dirZ = $"{driveZ}{shortcut}";

        if (Directory.Exists(dirF) && Directory.Exists(dirZ))
        {
            CreateShortcut(dirF, dirZ);
            CreateShortcut(dirZ, dirF);
        }
    }
}

private void CreateShortcut(string shortcutPath, string targetPath)
{
    WshShell wshShell = new WshShell();
    string fileName = Path.Combine(shortcutPath, $"{Application.ProductName}.lnk");
    IWshShortcut shortcut = (IWshShortcut)wshShell.CreateShortcut(fileName);
    shortcut.TargetPath = targetPath;
    shortcut.Save();
}

在創建目錄之前重命名 TreeNode 物件

這是一種根據Jimi 的建議重命名給定檔案夾的方法。

創建一個Dictionary<string, string>以將目標檔案夾作為鍵，將新名稱作為值。
對于每個TreeView控制元件，在臨時中克隆其節點TreeView以更改.Text目標節點的屬性，而不反映在主TreeView控制元件上。重命名父節點和/或子節點時，必須設定.Text屬性才能獲得正確的屬性。.FullPath

private void SomeButton_Click(object sender, EventArgs e)
{
    var driveF = "C:\\";
    var driveZ = "D:\\";
    var selDir = loremDropDown.SelectedValue.ToString();
    var destPathF = selDir.Replace(Path.GetPathRoot(selDir), driveF);
    var destPathZ = selDir.Replace(Path.GetPathRoot(selDir), driveZ);
    var treeSep = pathLorem.PathSeparator;
    var dirSep = Path.DirectorySeparatorChar.ToString();
    var shortcuts = new HashSet<string>();
    var dirsToRename = new Dictionary<string, string>
    {
        { "Book 4", "Book 1" },
        { "Book 5", "Book 2" },
        { "Book 6", "Book 3" },
        { "Books", "Books 123" }
    };

    using (var tv = new TreeView())
    {
        tv.Nodes.AddRange(pathLorem.Nodes
            .OfType<TreeNode>()
            .Select(n => n.Clone() as TreeNode)
            .ToArray());

        foreach (var node in GetCheckedNodes(tv.Nodes))
        {
            if (dirsToRename.ContainsKey(node.Text)) node.Text = dirsToRename[node.Text];
            var sPath = Path.Combine(destPathF, node.FullPath.Replace(treeSep, dirSep));
            Directory.CreateDirectory(sPath);
            if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveF.ToArray()));
        }

        tv.Nodes.Clear();
        tv.Nodes.AddRange(ipsumPath.Nodes
            .OfType<TreeNode>()
            .Select(n => n.Clone() as TreeNode)
            .ToArray());

        foreach (var node in GetCheckedNodes(tv.Nodes))
        {
            if (dirsToRename.ContainsKey(node.Text)) node.Text = dirsToRename[node.Text];
            var sPath = Path.Combine(destPathZ, node.FullPath.Replace(treeSep, dirSep));
            Directory.CreateDirectory(sPath);
            if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveZ.ToArray()));
        }

        foreach (var shortcut in shortcuts)
        {
            var dirF = $"{driveF}{shortcut}";
            var dirZ = $"{driveZ}{shortcut}";

            if (Directory.Exists(dirF) && Directory.Exists(dirZ))
            {
                CreateShortcut(dirF, dirZ);
                CreateShortcut(dirZ, dirF);
            }
        }
    }
}

根據目的地重命名給定的 TreeNode 物件

密鑰取自ComboBox控制元件。

private void btnTest_Click(object sender, EventArgs e)
{
    var driveF = "C:\\";
    var driveZ = "D:\\";
    var selDir = loremDropDown.SelectedValue.ToString();
    var destPathF = selDir.Replace(Path.GetPathRoot(selDir), driveF);
    var destPathZ = selDir.Replace(Path.GetPathRoot(selDir), driveZ);
    var treeSep = pathLorem.PathSeparator;
    var dirSep = Path.DirectorySeparatorChar.ToString();
    var shortcuts = new HashSet<string>();
    var dirsToRename = new Dictionary<string, string>
    {
        { "Book 1", "Book 4" },
        { "Book 2", "Book 5" },
        { "Book 3", "Book 6" }
    };

    foreach (var node in GetCheckedNodes(pathLorem.Nodes))
    {
        var sPath = Path.Combine(destPathF, node.FullPath.Replace(treeSep, dirSep));

        // Comment this if `pathLorem` is not the source of the keys...
        if (dirsToRename.ContainsKey(node.Text))
            sPath = Path.Combine(Path.GetDirectoryName(sPath), dirsToRename[node.Text]);

        Directory.CreateDirectory(sPath);

        if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveF.ToArray()));
    }

    foreach (var node in GetCheckedNodes(ipsumPath.Nodes))
    {
        var sPath = Path.Combine(destPathZ, node.FullPath.Replace(treeSep, dirSep));

        // Comment this if `ipsumPath` is not the source of the keys...
        if (dirsToRename.ContainsKey(node.Text))
            sPath = Path.Combine(Path.GetDirectoryName(sPath), dirsToRename[node.Text]);

        Directory.CreateDirectory(sPath);

        if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveZ.ToArray()));
    }

    foreach (var shortcut in shortcuts)
    {
        var dirF = $"{driveF}{shortcut}";
        var dirZ = $"{driveZ}{shortcut}";

        if (Directory.Exists(dirF) && Directory.Exists(dirZ))
        {
            CreateShortcut(dirF, dirZ);
            CreateShortcut(dirZ, dirF);
        }
    }
}

您可以添加一個控制元件，例如DataGridView獲取字典的鍵值對dirsToRename而不是硬代碼。

您可以通過分別呼叫和類的.Move方法來重命名系統檔案或目錄。FileDirectory

// Rename a file...
File.Move("source", "destination");

// Rename a directory...
Directory.Move("source", "destination");

將選定的目錄映射到另一個

要將選定目錄從映射ComboBox到另一個目錄，請根據目標（例如）目錄的位置更改destPathF或（不是兩者）。destPathZBook3_projects_render

例如：

private void SomeButton_Click(object sender, EventArgs e)
{
    var driveF = "C:\\";
    var driveZ = "D:\\";
    var selDirInfo = loremDropDown.SelectedItem as DirectoryInfo;
    var selDir = selDirInfo.FullName;
    var destPathF = selDir.Replace(Path.GetPathRoot(selDir), driveF);
    var destPathZ = selDir.Replace(Path.GetPathRoot(selDir), driveZ);
    var treeSep = pathLorem.PathSeparator;
    var dirSep = Path.DirectorySeparatorChar.ToString();
    var shortcuts = new HashSet<string>();
    var exDir = "Book 3";
    var repDir = "Book3_projects_render";
    bool isExDir = selDirInfo.Name == exDir;

    if (isExDir)
    {
        // If `Book3_projects_render` is on F: otherwise comment...
        //destPathF = Path.Combine(Path.GetDirectoryName(destPathF), "Book3_projects_render");

        // If `Book3_projects_render` is on Z: otherwise comment...
        destPathZ = Path.Combine(Path.GetDirectoryName(destPathZ), repDir);
    }

    foreach (var node in GetCheckedNodes(pathLorem.Nodes))
    {
        var sPath = Path.Combine(destPathF, node.FullPath.Replace(treeSep, dirSep));
        Directory.CreateDirectory(sPath);
        if (node.Level == 0) shortcuts.Add(sPath.Substring(driveF.Length));
    }

    foreach (var node in GetCheckedNodes(ipsumPath.Nodes))
    {
        var sPath = Path.Combine(destPathZ, node.FullPath.Replace(treeSep, dirSep));
        Directory.CreateDirectory(sPath);
        if (node.Level == 0) shortcuts.Add(sPath.Substring(driveZ.Length));
    }

    foreach (var shortcut in shortcuts)
    {
        var dirF = $"{driveF}{shortcut}";
        var dirZ = $"{driveZ}{shortcut}";

        if (isExDir)
        {
            // If `Book3_projects_render` is on Z: otherwise switch exDir and repDir...
            dirF = dirF.Replace($@"\{repDir}\", $@"\{exDir}\");
            dirZ = dirZ.Replace($@"\{exDir}\", $@"\{repDir}\");
        }

        if (Directory.Exists(dirF) && Directory.Exists(dirZ))
        {
            CreateShortcut(dirF, dirZ);
            CreateShortcut(dirZ, dirF);
        }
    }
}
